InitTCGLegacyInterface() locates the Legacy BIOS Protocol, optionally + the TCG2 Protocol, and loads two firmware volume files: + - LEGX16: The legacy BIOS 16-bit thunk layer (copied to F000-E000). + - TPM32: The TPM 1.2 legacy driver (copied to a page-aligned region). + - MPTPM: An optional multi-processor TPM binary. + 3. It then allocates TPM code space, installs callbacks, and patches the + BFI ($BIN) marker in the shadow area to complete the legacy interface. + 4. A LegacyBoot event is registered via CreateEventEx to unlink the + TPM driver when the OS boots. + + File: AmiModulePkg/TCG2/Common/TcgLegacy/TcgLegacy.c + Binary: TcgLegacy.efi (X64) + Size: ~8 KB (0x1FC0) + Source: AMI BIOS, HR650X platform + + Copyright (C) AMI Corporation.

Splitter driver that implements a console multiplexer for UEFI. It registers three driver binding protocols to aggregate multiple physical console devices into single logical console handles for ConOut, ConIn, and StdErr. The driver manages child device lists for text output, text input, simple pointer, and absolute pointer devices, allowing the UEFI console subsystem to transparently support multiple simultaneous console devices. - -## Key Functions - -- `ConSplitterTextOutDriverBindingSupported()` -- Tests if a controller supports text output -- `ConSplitterTextOutDriverBindingStart()` -- Starts text output on a controller -- `ConSplitterTextOutDriverBindingStop()` -- Stops text output on a controller -- `ConSplitterTextInDriverBindingSupported()` -- Tests if a controller supports text input -- `ConSplitterTextInDriverBindingStart()` -- Starts text input on a controller -- `ConSplitterTextInDriverBindingStop()` -- Stops text input on a controller -- `ConSplitterPointerDriverBindingSupported()` -- Tests if a controller supports pointer input -- `ConSplitterPointerDriverBindingStart()` -- Starts pointer input on a controller -- `ConSplitterPointerDriverBindingStop()` -- Stops pointer input on a controller - -## Dependencies - -- `EFI_SIMPLE_TEXT_OUTPUT_PROTOCOL` -- `EFI_SIMPLE_TEXT_INPUT_PROTOCOL` -- `EFI_GRAPHICS_OUTPUT_PROTOCOL` -- `EFI_SIMPLE_POINTER_PROTOCOL` -- `EFI_ABSOLUTE_POINTER_PROTOCOL` -- `EFI_DEVICE_PATH_PROTOCOL` -- `EFI_SERIAL_IO_PROTOCOL` -- `EFI_HII_DATABASE_PROTOCOL` -- `EFI_UGA_DRAW_PROTOCOL` -- `gEfiConsoleOutDeviceGuid` / `gEfiGlobalVariableGuid` (ConOutDev/ConInDev UEFI variables) - -## Platform - -- **Architecture**: x86-64 (PE32+) -- **Subsystem**: EFI_BOOT_SERVICE_DRIVER (0x0B) -- **Source**: AmiModulePkg / MdeModulePkg -- **BIOS**: HR650X (HR6N0XMLK) \ No newline at end of file diff --git a/CpPlatPkg/Uba/CfgDb/Pei/UbaConfigDatabasePei/README.md b/CpPlatPkg/Uba/CfgDb/Pei/UbaConfigDatabasePei/README.md new file mode 100644 index 0000000..8db9e6b --- /dev/null +++ b/CpPlatPkg/Uba/CfgDb/Pei/UbaConfigDatabasePei/README.md @@ -0,0 +1,31 @@ +# UbaConfigDatabasePei + +| Index | Module | Size | Phase | +|-------|--------|------|-------| +| 366 | UbaConfigDatabasePei | 7.5 KB (7,716 B) | PEI | + +## Overview + +UBA (UEFI BIOS Abstraction) Configuration Database PEIM from American Megatrends.

The chain is: + +| Order | Function | Purpose | +|-------|----------|---------| +| 1 | `sub_6D8` (0x6D8) | Init gImageHandle, gST, gBS (BootServices) | +| 2 | `sub_774` (0x774) | Init gRT (RuntimeServices) | +| 3 | `sub_7B0` (0x7B0) | Init gSmst (SMM Services Table), locate SMM Base2 protocol | +| 4 | `sub_C3C` (0xC3C) | Get SMRAM ranges via SMM Access Protocol | +| 5 | `sub_EB8` (0xEB8) | Thunk to SMM PCI MMIO base init | +| 6 | `sub_EBC` (0xEBC) | Init PCI MMIO base (DxeMmPciBase) | +| 7 | `sub_F78` (0xF78) | Get PCD value (token 5) - platform configuration | +| 8 | `sub_10EC` (0x10EC) | Init HOB list | +| 9 | `sub_11A0` (0x11A0) | ACPI PM timer delay + WHEA boot protocol init | +| 10 | `sub_13B0` (0x13B0) | MP sync data table init (per-CPU structures) | +| 11 | `sub_1ACC` (0x1ACC) | WHEA silicon hooks: resolve all remaining protocols | +| 12 | `sub_1868` (0x1868) | CPU topology detection (thread/core bits via CPUID) | + +### Protocol Resolution (`sub_1ACC`) + +Looked-up protocols at 0x3E70, 0x3E40 (MP), 0x3E80 (gEfiWheaBootProtocolGuid), 0x3E90 + HOB GUID at 0x3D90. + +The function `sub_1154` searches the HOB list for a specific GUID (at 0x3D90: `5138B5C5-9369-48EC-5B97-38A2F7096675`). The HOB data offset +24 is stored at `qword_4148` as a pointer to the WHEA silicon configuration data. + +### Error Record Processing (`sub_2C04`) + +The SMI handler at 0x2C04 is the core error logging function: + +1. Checks if `byte_40A0` is set (WHEA logging enabled). Returns `EFI_NOT_READY` if not. +2. Calls `sub_2EF0` to check if error status blocks are pre-initialized. If not, initialize them. +3. Extracts error record details from the input context (offset +128 from `a1` / CommunicationBuffer). +4. Calls `sub_1F04` to determine error record subtype. If it matches 0x3EC0 (Corrected/PCIe), performs ID translation via `sub_1E70`. +5. Calls `sub_26AC` to find the appropriate error status block entry by severity (1 or 2). +6. Extracts a pointer from the error status block entry. +7. Determines error severity (192=non-fatal, 80=corrected, 228=fatal) based on source GUID matching (0x3EA0, 0x3EB0, 0x3EC0, 0x3ED0, 0x3EE0) and policy config. +8. If the error source matches the policy config, fills in the error record: + - Sets severity flags + - Copies error timestamp + - Sets error source GUID + - Copies FRU (Field Replaceable Unit) text if present (16/20 bytes) + - Copies error data payload of variable size (n192 bytes) +9. Updates the error block header fields (length, severity flags). + +## State Management + +### Global Variables + +| Address | Name | Size | Purpose | +|---------|------|------|---------| +| 0x4098 | `qword_4098` | 8 | Error status accumulator / global init status | +| 0x40A0 | `byte_40A0` | 1 | WHEA logging enabled flag | +| 0x40A1 | `byte_40A1` | 1 | Dual-rank/dual-socket error pending flag | +| 0x40A2 | `byte_40A2` | 1 | Single-rank/single-socket error pending flag | +| 0x40A3 | `byte_40A3` | 1 | Error status blocks initialized flag | +| 0x40A8 | `SystemTable` | 8 | EFI System Table (gST) | +| 0x40B0 | `BootServices` | 8 | EFI Boot Services (gBS) | +| 0x40B8 | `qword_40B8` | 8 | Image handle (gImageHandle) | +| 0x40C0 | `qword_40C0` | 8 | Runtime Services (gRT) | +| 0x40C8 | `qword_40C8` | 8 | SMM System Table (gSmst) | +| 0x40D8 | `qword_40D8` | 8 | PCI MMIO base protocol pointer | +| 0x40E0 | `qword_40E0` | 8 | PCD value (token 5) | +| 0x40E8 | `qword_40E8` | 8 | HOB list pointer (VendorTable) | +| 0x40F0 | `qword_40F0` | 8 | MP sync data protocol pointer | +| 0x40F8 | `qword_40F8` | 8 | SMM Base2 protocol pointer | +| 0x4100 | `qword_4100` | 8 | SMM MP protocol pointer | +| 0x4108 | `unk_4108` | ... | MP sync data structure | +| 0x4110 | `qword_4110` | 8 | Number of WHEA error source entries | +| 0x4126 | `unk_4126` | ... | WHEA error source array (variable, 26 bytes per entry) | +| 0x4138 | `unk_4138` | 8 | MP Service protocol pointer (saved) | +| 0x4140 | `unk_4140` | 8 | SmmCpu protocol pointer (saved) | +| 0x4148 | `qword_4148` | 8 | WHEA silicon HOB data pointer (+24) | +| 0x4150 | `unk_4150` | 8 | WHEA Boot protocol pointer | +| 0x4158 | `unk_4158` | 8 | Saved protocol pointer | +| 0x4160 | `qword_4160` | 8 | PCD protocol pointer | +| 0x4170 | `unk_4170` | ... | WHEA silicon config data structure (328 bytes) | +| 0x4178 | `qword_4178` | 8 | Policy configuration data pointer (from SMM protocol) | +| 0x4180 | `qword_4180` | 8 | SMM CPU Service protocol pointer | +| 0x42E8 | `unk_42E8` | ... | WHEA silicon hooks config | +| 0x42F0 | `unk_42F0` | 8 | Protocol pointer | + +### Per-CPU Data Structures (initialized in `sub_13B0`) + +Three parallel arrays indexed by CPU (up to 512 CPUs): + +| Address | Name | Element Size | Purpose | +|---------|------|-------------|---------| +| 0x9320 | `byte_9320` | 1 | Per-CPU active flag | +| 0x9B20 | `qword_9B20` | 8 | Per-CPU APIC ID map | +| 0xDB20 | `dword_DB20` | 4 | Per-CPU register values | +| 0xFB20 | `byte_FB20` | 1 | Per-CPU status (0=inactive, 1=active, 2=running) | + +Also: +| 0x4308 | `byte_4308` | 40 | Per-CPU (up to 0x5000/40=512) sync data structure header | + +Layout: `[64 * (socket + 448 * package)] [socket offset = 64, package stride = 448 * 64]` + +### SpinLocks +| 0x9308 | `unk_9308` | 8 | SpinLock for MP sync | +| 0x9310 | `unk_9310` | 8 | SpinLock for MP sync | + +### SMRAM Range Info +| 0x25328 | `qword_25328` | 8 | Number of SMRAM descriptors (total_size >> 5) | +| 0x25330 | `qword_25330` | 8 | SMRAM range descriptor array pointer | + +### WHEA Error Status Block Table (at 0x3F28) + +Entry structure (24 bytes per entry): +``` +Offset Size Field +0x00 2 Type/severity level (1 or 2 = corrected or non-fatal) +0x02 4 Data size +0x08 8 Pointer to error status block structure +0x10 8 Pointer to error source specific data +``` + +Entry count at `qword_3F90`.

-## Overview - -GraphicsConsole is a UEFI DXE driver that implements `EFI_SIMPLE_TEXT_OUTPUT_PROTOCOL` on top of `EFI_GRAPHICS_OUTPUT_PROTOCOL`. It provides a text rendering pipeline that accumulates characters in an output buffer, flushes lines on newline or wrap events using the HII_FONT protocol's StringToImage service, and outputs via GOP Bit Block Transfer (Blt). The driver manages text mode settings, cursor positioning, and character attribute rendering in a graphical framebuffer environment. - -## Key Functions - -- `ModuleEntryPoint()` -- Standard UEFI module entry point -- `TextOutOutputString()` -- Outputs a string to the graphical console -- `TextOutSetModeCallback()` -- Sets the text output mode (resolution / columns x rows) -- `FlushCurrentLine()` -- Flushes buffered text to the framebuffer via GOP Blt -- `TextOutReset()` -- Resets the text output device -- `TextOutSetAttribute()` -- Sets text foreground/background color attributes -- `TextOutClearScreen()` -- Clears the graphical console screen -- `TextOutEnableCursor()` -- Enables or disables the cursor -- `TextOutSetCursorPosition()` -- Positions the text cursor - -## Dependencies - -- `EFI_GRAPHICS_OUTPUT_PROTOCOL` (GOP) -- Pixel-level framebuffer access -- `EFI_HII_FONT_PROTOCOL` -- Font rendering and StringToImage service -- `EFI_SIMPLE_TEXT_OUTPUT_PROTOCOL` -- Output protocol produced by this driver - -## Platform - -- **Architecture**: x86-64 (PE32+) -- **PDB**: GraphicsConsole.pdb -- **Subsystem**: EFI_BOOT_SERVICE_DRIVER (0x0B) -- **Source**: MdeModulePkg (Intel) -- **BIOS**: HR650X (HR6N0XMLK) \ No newline at end of file diff --git a/HeciInit/HeciInit.c b/HeciInit/HeciInit.c deleted file mode 100644 index d41a700..0000000 --- a/HeciInit/HeciInit.c +++ /dev/null @@ -1,1891 +0,0 @@ -/** @file - HeciInit.c - HECI (Host Embedded Controller Interface) Initialization PEIM - - This PEIM initializes the HECI interface (both HECI-1 and HECI-2) during the - PEI phase.

(.text, .rdata, .data, section_3, .xdata, .reloc) | + +## Overview + +ConSplitter is an AMI Console Splitter driver that implements a console multiplexer for UEFI. It registers three driver binding protocols to aggregate multiple physical console devices into single logical console handles for ConOut, ConIn, and StdErr. The driver manages child device lists for text output, text input, simple pointer, and absolute pointer devices, allowing the UEFI console subsystem to transparently support multiple simultaneous console devices. + +## Key Functions + +- `ConSplitterTextOutDriverBindingSupported()` -- Tests if a controller supports text output +- `ConSplitterTextOutDriverBindingStart()` -- Starts text output

UEFI DXE driver that implements `EFI_SIMPLE_TEXT_OUTPUT_PROTOCOL` on top of `EFI_GRAPHICS_OUTPUT_PROTOCOL`. It provides a text rendering pipeline that accumulates characters in an output buffer, flushes lines on newline or wrap events using the HII_FONT protocol's StringToImage service, and outputs via GOP Bit Block Transfer (Blt). The driver manages text mode settings, cursor positioning, and character attribute rendering in a graphical framebuffer environment. + +## Key Functions + +- `ModuleEntryPoint()` -- Standard UEFI module entry point +- `TextOutOutputString()` -- Outputs a string to the graphical console +- `TextOutSetModeCallback()` -- Sets the text output mode (resolution / columns x rows) +- `FlushCurrentLine()` -- Flushes buffered text to the framebuffer via GOP Blt +- `TextOutReset()` -- Resets the text output device +- `TextOutSetAttribute()` -- Sets text foreground/background color attributes +- `TextOutClearScreen()` -- Clears the graphical console screen +- `TextOutEnableCursor()` -- Enables or disables the cursor +- `TextOutSetCursorPosition()` -- Positions the text cursor + +## Dependencies + +- `EFI_GRAPHICS_OUTPUT_PROTOCOL` (GOP) -- Pixel-level framebuffer access +- `EFI_HII_FONT_PROTOCOL` -- Font rendering and StringToImage service +- `EFI_SIMPLE_TEXT_OUTPUT_PROTOCOL` -- Output protocol produced by this driver + +## Platform + +- **Architecture**: x86-64 (PE32+) +- **PDB**: GraphicsConsole.pdb +- **Subsystem**: EFI_BOOT_SERVICE_DRIVER (0x0B) +- **Source**: MdeModulePkg (Intel) +- **BIOS**: HR650X (HR6N0XMLK) \ No newline at end of file diff --git a/MdeModulePkg/Universal/DevicePathDxe/DevicePathDxe.c b/MdeModulePkg/Universal/DevicePathDxe/DevicePathDxe.c new file mode 100644 index 0000000..78d5d8a --- /dev/null +++ b/MdeModulePkg/Universal/DevicePathDxe/DevicePathDxe.c @@ -0,0 +1,1032 @@ +/* + * DevicePathDxe.c - UEFI Device Path DXE Driver + * Module: DevicePathDxe.efi (from Lenovo HR650X BIOS) + * SHA256: 9139a18c6d78dc89a880b0944c1833e2ae37cda701ca74670f086e65d28ad5bd + * + * This driver implements three UEFI device path protocol libraries: + * - DevicePathUtilities: Core device path node manipulation + * - DevicePathToText: Convert device path to human-readable text + * - DevicePathFromText: Parse text representation back to device path + * + * The entry point installs these three protocol interfaces via + * gBS->InstallMultipleProtocolInterfaces(): + * - EFI_DEVICE_PATH_UTILITIES_PROTOCOL + * - EFI_DEVICE_PATH_TO_TEXT_PROTOCOL + * - EFI_DEVICE_PATH_FROM_TEXT_PROTOCOL + * + * File Structure (address ranges): + * 0x000 - 0x2C0 PE/COFF header + * 0x2C0 - 0x7E20 .text (code) + * 0x7E20 - 0xAE20 .rdata (strings, format strings, dispatch tables) + * 0xAE20 - 0xB4E0 .data (protocol GUIDs, globals) + * 0xB4E0 - 0xBCA0 seg004 (more read-only data) + * 0xBCA0 - 0xC020 .xdata (exception handling) + * 0xC020 - 0xC280 .reloc (base relocations) + */ + +#include "Tcg2Dxe.h" /* Not actually Tcg2 but we keep project convention */ +/* NOTE: This file is a decompiled representation of the UEFI device path + * protocol driver.

Each slot entry has a 10-byte descriptor containing: - -| Offset | Size | Description | -|--------|------|-------------| -| +0 | 2 | Slot StringId (name) - if non-zero, string is fetched and written | -| +2 | 1 | Slot Type (SMBIOS slot type enumeration) | -| +3 | 1 | Slot Data Bus Width | -| +4 | 1 | Current Usage | -| +5 | 1 | Slot Length | -| +6 | 1 | Characteristics (low byte) | -| +7 | 1 | Characteristics (high byte) | -| +8 | 1 | Segment Number (Group) | -| +9 | 1 | Bus Number / Function Number | - -The slot string data is embedded in the code as an array of packed structures starting at offset 0x7A5. - -Each slot can have a name string and/or a description string. These are retrieved via `HiiGetString()` from the HII database and written to the UBA SMBIOS data store via `UbaSmbiosUpdateStringReplace()`. - -After all slots are processed, `UbaSmbiosDeleteAllKeysOfType(9)` removes stale Type 9 entries. - -## SMBIOS Type 41 - Onboard Devices - -The function `UpdateSmbiosType41OnboardDevices()` handles up to 8 onboard device entries. Similar pattern: for each device index, it reads configuration data, resolves string references via HII, and updates the UBA SMBIOS data store. - -After processing, `UbaSmbiosDeleteAllKeysOfType(41)` removes stale Type 41 entries. - -## SMBIOS Extended Type - -The function `UpdateSmbiosTypeUnknownExtended()` handles 4 entries of an additional type (likely a platform-specific OEM SMBIOS type). This function could not be decompiled (possibly due to optimization artifacts or inline assembly), but follows the same pattern of index-based iteration with HII string resolution and UBA data store updates. - -## Key Data Flow - -1. **HII String Packages**: The driver registers HII string packages containing platform-specific SMBIOS strings (slot names, device descriptions). - -2. **UBA Protocol**: Uses UBA private protocol (`gSmbiosStringPackHandle`) to manage SMBIOS string data through set/get/delete operations. - -3. **PCI Access**: Uses `mPciUsra` (PCI MMCONFIG base protocol) for PCI register access via `PciWriteMmPciUsra()`. - -4. **Variable Storage**: Uses UEFI variable services through `UbaSmbiosGetVariable()` / `UbaSmbiosSetVariableIfNotExist()` for persistent key-value storage. - -## Renamed Functions (40 new names) - -| Address | Original | Renamed To | Size | Purpose | -|---------|----------|------------|------|---------| -| 0x280 | sub_280 | InternalZeroMem |

- Base UEFI types and libraries -- `MdeModulePkg` - UEFI HII services -- `PurleyPlatPkg` - UBA platform library -- `CpRcPkg` - PCI MMCONFIG base library - -## Notes - -- The module is compiled with **DEBUG_VS2015** configuration, meaning all ASSERT macros are active. -- The UBA protocol GUIDs and HII package data are embedded in the module's .data and seg004 sections. -- String replacement in `UbaSmbiosUpdateStringReplace()` is done in-place within the SMBIOS string block buffer. -- The driver uses a callback model: the UBA layer invokes `SmbiosDataUpdateCallback()` at the appropriate time for SMBIOS data customization. -- The platform name **NeonCityEPRP** suggests this is for Intel Purley server platforms with a specific board revision. - diff --git

Each slot entry has a 10-byte descriptor containing: + +| Offset | Size | Description | +|--------|------|-------------| +| +0 | 2 | Slot StringId (name) - if non-zero, string is fetched and written | +| +2 | 1 | Slot Type (SMBIOS slot type enumeration) | +| +3 | 1 | Slot Data Bus Width | +| +4 | 1 | Current Usage | +| +5 | 1 | Slot Length | +| +6 | 1 | Characteristics (low byte) | +| +7 | 1 | Characteristics (high byte) | +| +8 | 1 | Segment Number (Group) | +| +9 | 1 | Bus Number / Function Number | + +The slot string data is embedded in the code as an array of packed structures starting at offset 0x7A5. + +Each slot can have a name string and/or a description string. These are retrieved via `HiiGetString()` from the HII database and written to the UBA SMBIOS data store via `UbaSmbiosUpdateStringReplace()`. + +After all slots are processed, `UbaSmbiosDeleteAllKeysOfType(9)` removes stale Type 9 entries. + +## SMBIOS Type 41 - Onboard Devices + +The function `UpdateSmbiosType41OnboardDevices()` handles up to 8 onboard device entries. Similar pattern: for each device index, it reads configuration data, resolves string references via HII, and updates the UBA SMBIOS data store. + +After processing, `UbaSmbiosDeleteAllKeysOfType(41)` removes stale Type 41 entries. + +## SMBIOS Extended Type + +The function `UpdateSmbiosTypeUnknownExtended()` handles 4 entries of an additional type (likely a platform-specific OEM SMBIOS type). This function could not be decompiled (possibly due to optimization artifacts or inline assembly), but follows the same pattern of index-based iteration with HII string resolution and UBA data store updates. + +## Key Data Flow + +1. **HII String Packages**: The driver registers HII string packages containing platform-specific SMBIOS strings (slot names, device descriptions). + +2. **UBA Protocol**: Uses UBA private protocol (`gSmbiosStringPackHandle`) to manage SMBIOS string data through set/get/delete operations. + +3. **PCI Access**: Uses `mPciUsra` (PCI MMCONFIG base protocol) for PCI register access via `PciWriteMmPciUsra()`. + +4. **Variable Storage**: Uses UEFI variable services through `UbaSmbiosGetVariable()` / `UbaSmbiosSetVariableIfNotExist()` for persistent key-value storage. + +## Renamed Functions (40 new names) + +| Address | Original | Renamed To | Size | Purpose | +|---------|----------|------------|------|---------| +| 0x280 | sub_280 | InternalZeroMem | 0x20 | Zero memory helper | +| 0x300 | sub_300 | InternalCopyMem | 0x42 | Copy memory helper | +| 0x370 | _ModuleEntryPoint | _ModuleEntryPoint | 0x1C | Entry point | +| 0x38C | sub_38C | UefiDriverEntryPoint | 0x2C7 | Driver initialization | +| 0x654 | sub_654 | SmbiosDataUpdateEntry | 0x125 | Main entry -

Operating in SMM ensures that flash write operations are protected from OS interference and that only authenticated update requests are processed. - -## Key Functions - -- **ModuleEntryPoint** -- Standard SMM driver entry; library init and reflash setup -- **sub_494** -- AutoGen library constructor -- **sub_744** -- Core reflash SMM logic (flash detection, write enable, erase/program sequences) -- **sub_10F0** -- Error handler / cleanup for reflash failures - -## Protocols - -- **SmmBase2 Protocol** -- SMM entry point -- **SmmSpiProtocol** -- SPI flash controller access from SMM -- **FirmwareVolumeBlock Protocol** (SMM) -- Block-level flash access -- **SmmCommunication Protocol** -- For receiving flash commands from DXE - -## Platform - -- **Build:** HR6N0XMLK DEBUG_VS2015 X64 -- **Source:** AmiModulePkg/ReFlashSmm -- **Part of:** HR650X BIOS SMM infrastructure (indices 0195-0199, 0201-0203) \ No newline at end of file diff --git a/ReFlashSmm/ReFlashSmm.c b/ReFlashSmm/ReFlashSmm.c deleted file mode 100644 index 12afda1..0000000 --- a/ReFlashSmm/ReFlashSmm.c +++ /dev/null @@ -1,27 +0,0 @@ -/** @file - ReFlashSmm.c -- ReFlashSmm - - Auto-converted from IDA decompiler output. - Functions: 1 - -Copyright (c) HR650X BIOS Decompilation Project -**/ - -#include "ReFlashSmm.h" - - -// Function: ModuleEntryPoint -EFI_STATUS -ModuleEntryPoint( - EFI_HANDLE ImageHandle, - EFI_SYSTEM_TABLE *SystemTable - ) -{ - signed __int64 v2; // rbx - - sub_494(ImageHandle, SystemTable); - v2 = sub_744(); - if ( v2 < 0 ) - sub_10F0(qword_26A8); - return v2; -} diff --git a/ReFlashSmm/ReFlashSmm.h b/ReFlashSmm/ReFlashSmm.h deleted file mode 100644 index 7d42046..0000000 --- a/ReFlashSmm/ReFlashSmm.h +++ /dev/null @@ -1,53 +0,0 @@ -/** @file - ReFlashSmm.h -- Header for ReFlashSmm - - -Copyright (c) HR650X BIOS Decompilation Project -**/ - -#ifndef __REFLASHSMM_H__ -#define __REFLASHSMM_H__ - -#include "../uefi_headers/Uefi.h" - -// -// Function Prototypes -// - -/// -/// ModuleEntryPoint -- UEFI entry point / initialization function -/// -EFI_STATUS -EFIAPI -ModuleEntryPoint( - VOID -); - -/// -/// sub_494 -/// -EFI_STATUS -EFIAPI -sub_494( - VOID -); - -/// -/// sub_744 -/// -EFI_STATUS -EFIAPI -sub_744( - VOID -); - -/// -/// sub_10F0 -/// -EFI_STATUS -EFIAPI -sub_10F0( - VOID -); - -#endif /* __REFLASHSMM_H__ */ \ No newline at end of file diff --git a/ReFlashSmm/ReFlashSmm.md b/ReFlashSmm/ReFlashSmm.md deleted file mode 100644 index 356573b..0000000 --- a/ReFlashSmm/ReFlashSmm.md +++ /dev/null @@ -1,11 +0,0 @@ -# ReFlashSmm - -## Function Table - -| Address | Name | Description | -|---------|------|-------------| -| | **ModuleEntryPoint** | | -| rbx | **sub_494(ImageHandle, SystemTable); v2 = sub_744(); if ( v2 < 0 ) sub_10F0(qword_26A8); return v2; }** | | - ---- -*Generated by HR650X BIOS Decompilation Project* \ No newline at end of file diff --git a/RegAccessDxe/README.md b/RegAccessDxe/README.md deleted file mode 100644 index 9c06348..0000000 --- a/RegAccessDxe/README.md +++ /dev/null @@ -1,15 +0,0 @@ -# RegAccessDxe, 0095, 0x5800 (22528 bytes), Phase 2 - -Register Access DXE driver providing PCIe/IIO register address translation for Intel Xeon Scalable platforms.

CMOS Debug Level Control: DebugPrint reads the CMOS diagnostic - register (0x4B) via RTC ports 0x70/0x71 to determine the platform's - configured debug verbosity level. Level 1 shows errors only; higher - levels show progressively more debug output. - -2. Hardware Strapping: When CMOS debug level is 0, the driver falls - back to reading a hardware strap/pin configuration from memory-mapped - I/O at 0xFDAF0490 (bit 1) to determine the debug level. - -3. HOB GUID Matching: GetHobList iterates through the UEFI HOB - (Hand-off Block) list looking for a specific HOB by GUID. The GUID - is stored split across gTargetHobGuid_lo and gTargetHobGuid_hi - for comparison purposes. - -4. Protocol Registration: ModuleEntryPoint locates the SetupConfig - protocol via gBS->LocateProtocol and then calls a registration - function at offset +16 in the protocol interface to register for - configuration update notifications. The registration includes a - 24-byte context block. - -5. The driver name contains "NeonCityEPRP" which identifies it as a - platform-specific DXE driver for the NeonCity platform's EPRP - (Enhanced Platform Reliability Profile) configuration. The "UBA:" - prefix on the debug string indicates usage of AMI's UBA (Universal - BIOS Architecture) framework. \ No newline at end of file diff --git a/SetupConfigUpdateDxeNeonCityEPRP/README.md b/SetupConfigUpdateDxeNeonCityEPRP/README.md deleted file mode 100644 index 5dbf664..0000000 --- a/SetupConfigUpdateDxeNeonCityEPRP/README.md +++ /dev/null @@ -1,26 +0,0 @@ -# SetupConfigUpdateDxeNeonCityEPRP - -| Index | Module | Size | Phase | -|-------|--------|------|-------| -| 0346 | SetupConfigUpdateDxeNeonCityEPRP | 3,232 bytes | DXE | - -Small UEFI DXE driver (~3.2 KB, 8 functions) that registers a notification callback with the SetupConfig protocol for the NeonCity EPRP platform.

With 586 functions spanning UNDI, SNP, PXE, NVM, PHY, MAC, iSCSI, SPI, and management protocol layers, it provides complete network initialization including EEPROM/ROM parsing, PHY configuration, flash (SPI) access, PXE ROM setup, and iSCSI offload. The module registers a network controller driver with the UEFI boot manager and installs UNDI child protocol instances. - -## Key Functions - -- **ModuleEntryPoint** -- Main entry point; calls EarlyInit, installs protocol teardown, dispatches DxeDriverEntryPoint -- **EarlyInit** -- One-time initialization: registers protocol notification callbacks -- **DxeDriverEntryPoint** -- DXE driver entry;

Coordinates with the SMM watchdog handler via the SMM Communication Protocol to synchronize watchdog state between DXE and SMM phases. - -## Key Functions - -- **WatchdogTimerDriverEntry** -- Module entry point; installs the Watchdog Timer Architectural Protocol -- **WatchdogTimerRegisterHandler** -- Registers a notification handler to be called on watchdog expiry -- **WatchdogTimerSetTimerPeriod** -- Sets the watchdog timer period and enables/disables the watchdog -- **WatchdogTimerGetTimerPeriod** -- Returns the current watchdog timer period -- **WatchdogTimerHandler** -- Internal handler invoked on timer expiry; calls registered notification then resets system -- **WatchdogSmmSync** -- Synchronizes watchdog state with the SMM watchdog handler - -## Protocols / Dependencies - -- EFI_WATCHDOG_TIMER_ARCH_PROTOCOL (gEfiWatchdogTimerArchProtocolGuid) -- {665E3FF5-46CC-11D4-9A38-0090273FC14D} -- EFI_SMM_COMMUNICATION_PROTOCOL -- Communication with SMM watchdog handler -- EFI_RUNTIME_SERVICES -- ResetSystem() for system reset on watchdog expiry -- UEFI Boot Services -- Protocol installation and timer management -- HOB List -- Access to HOB data for debug output device detection - -## Platform - -HR650X BIOS, x86-64 architecture.

SMI handler for SwSmi 158: Disables WHEA error logging (`byte_40A0 = 0`), releases PCI MMIO base -- **`sub_2C04`** (0x2C04) - SMI handler registered via `sub_26F4` callback (caller protocol): Processes WHEA error records, reads CPER data from error sources, writes them into the error status block -- **`sub_2FA8`** (0x2FA8) - SMM notification callback: Clears WHEA state flags (byte_40A1, byte_40A2, byte_40A3) - -## Internal Helpers - -### Initialization Chain (from `sub_21C0`) - -`sub_21C0` calls 14 init functions in sequence. Each call is wrapped in ASSERT_EFI_ERROR. The chain is: - -| Order | Function | Purpose | -|-------|----------|---------| -| 1 | `sub_6D8` (0x6D8) | Init gImageHandle, gST, gBS (BootServices) | -| 2 | `sub_774` (0x774) | Init gRT (RuntimeServices) | -| 3 | `sub_7B0` (0x7B0) | Init gSmst (SMM Services Table), locate SMM Base2 protocol | -| 4 | `sub_C3C` (0xC3C) | Get SMRAM ranges via SMM Access Protocol | -| 5 | `sub_EB8` (0xEB8) | Thunk to SMM PCI MMIO base init | -| 6 | `sub_EBC` (0xEBC) | Init PCI MMIO base (DxeMmPciBase) | -| 7 | `sub_F78` (0xF78) | Get PCD value (token 5) - platform configuration | -| 8 | `sub_10EC` (0x10EC) | Init HOB list | -| 9 | `sub_11A0` (0x11A0) | ACPI PM timer delay + WHEA boot protocol init | -| 10 | `sub_13B0` (0x13B0) | MP sync data table init (per-CPU structures) | -| 11 | `sub_1ACC` (0x1ACC) | WHEA silicon hooks: resolve all remaining protocols | -| 12 | `sub_1868` (0x1868) | CPU topology detection (thread/core bits via CPUID) | - -### Protocol Resolution (`sub_1ACC`) - -Looked-up protocols at 0x3E70, 0x3E40 (MP), 0x3E80 (gEfiWheaBootProtocolGuid), 0x3E90 + HOB GUID at 0x3D90. - -The function `sub_1154` searches the HOB list for a specific GUID (at 0x3D90: `5138B5C5-9369-48EC-5B97-38A2F7096675`). The HOB data offset +24 is stored at `qword_4148` as a pointer to the WHEA silicon configuration data. - -### Error Record Processing (`sub_2C04`) - -The SMI handler at 0x2C04 is the core error logging function: - -1. Checks if `byte_40A0` is set (WHEA logging enabled). Returns `EFI_NOT_READY` if not. -2. Calls `sub_2EF0` to check if error status blocks are pre-initialized. If not, initialize them. -3. Extracts error record details from the input context (offset +128 from `a1` / CommunicationBuffer). -4. Calls `sub_1F04` to determine error record subtype. If it matches 0x3EC0 (Corrected/PCIe), performs ID translation via `sub_1E70`. -5. Calls `sub_26AC` to find the appropriate error status block entry by severity (1 or 2). -6. Extracts a pointer from the error status block entry. -7. Determines error severity (192=non-fatal, 80=corrected, 228=fatal) based on source GUID matching (0x3EA0, 0x3EB0, 0x3EC0, 0x3ED0, 0x3EE0) and policy config. -8. If the error source matches the policy config, fills in the error record: - - Sets severity flags - - Copies error timestamp - - Sets error source GUID - - Copies FRU (Field Replaceable Unit) text if present (16/20 bytes) - - Copies error data payload of variable size (n192 bytes) -9. Updates the error block header fields (length, severity flags). - -## State Management - -### Global Variables - -| Address | Name | Size | Purpose | -|---------|------|------|---------| -| 0x4098 | `qword_4098` | 8 | Error status accumulator / global init status | -| 0x40A0 | `byte_40A0` | 1 | WHEA logging enabled flag | -| 0x40A1 | `byte_40A1` | 1 | Dual-rank/dual-socket error pending flag | -| 0x40A2 | `byte_40A2` | 1 | Single-rank/single-socket error pending flag | -| 0x40A3 | `byte_40A3` | 1 | Error status blocks initialized flag | -| 0x40A8 | `SystemTable` | 8 | EFI System Table (gST) | -| 0x40B0 | `BootServices` | 8 | EFI Boot Services (gBS) | -| 0x40B8 | `qword_40B8` | 8 | Image handle (gImageHandle) | -| 0x40C0 | `qword_40C0` | 8 | Runtime Services (gRT) | -| 0x40C8 | `qword_40C8` | 8 | SMM System Table (gSmst) | -| 0x40D8 | `qword_40D8` | 8 | PCI MMIO base protocol pointer | -| 0x40E0 | `qword_40E0` | 8 | PCD value (token 5) | -| 0x40E8 | `qword_40E8` | 8 | HOB list pointer (VendorTable) | -| 0x40F0 | `qword_40F0` | 8 | MP sync data protocol pointer | -| 0x40F8 | `qword_40F8` | 8 | SMM Base2 protocol pointer | -| 0x4100 | `qword_4100` | 8 | SMM MP protocol pointer | -| 0x4108 | `unk_4108` | ... | MP sync data structure | -| 0x4110 | `qword_4110` | 8 | Number of WHEA error source entries | -| 0x4126 | `unk_4126` | ... | WHEA error source array (variable, 26 bytes per entry) | -| 0x4138 | `unk_4138` | 8 | MP Service protocol pointer (saved) | -| 0x4140 | `unk_4140` | 8 | SmmCpu protocol pointer (saved) | -| 0x4148 | `qword_4148` | 8 | WHEA silicon HOB data pointer (+24) | -| 0x4150 | `unk_4150` | 8 | WHEA Boot protocol pointer | -| 0x4158 | `unk_4158` | 8 | Saved protocol pointer | -| 0x4160 | `qword_4160` | 8 | PCD protocol pointer | -| 0x4170 | `unk_4170` | ... | WHEA silicon config data structure (328 bytes) | -| 0x4178 | `qword_4178` | 8 | Policy configuration data pointer (from SMM protocol) | -| 0x4180 | `qword_4180` | 8 | SMM CPU Service protocol pointer | -| 0x42E8 | `unk_42E8` | ... | WHEA silicon hooks config | -| 0x42F0 | `unk_42F0` | 8 | Protocol pointer | - -### Per-CPU Data Structures (initialized in `sub_13B0`) - -Three parallel arrays indexed by CPU (up to 512 CPUs): - -| Address | Name | Element Size | Purpose | -|---------|------|-------------|---------| -| 0x9320 | `byte_9320` | 1 | Per-CPU active flag | -| 0x9B20 | `qword_9B20` | 8 | Per-CPU APIC ID map | -| 0xDB20 | `dword_DB20` | 4 | Per-CPU register values | -| 0xFB20 | `byte_FB20` | 1 | Per-CPU status (0=inactive, 1=active, 2=running) | - -Also: -| 0x4308 | `byte_4308` | 40 | Per-CPU (up to 0x5000/40=512) sync data structure header | - -Layout: `[64 * (socket + 448 * package)] [socket offset = 64, package stride = 448 * 64]` - -### SpinLocks -| 0x9308 | `unk_9308` | 8 | SpinLock for MP sync | -| 0x9310 | `unk_9310` | 8 | SpinLock for MP sync | - -### SMRAM Range Info -| 0x25328 | `qword_25328` | 8 | Number of SMRAM descriptors (total_size >> 5) | -| 0x25330 | `qword_25330` | 8 | SMRAM range descriptor array pointer | - -### WHEA Error Status Block Table (at 0x3F28) - -Entry structure (24 bytes per entry): -``` -Offset Size Field -0x00 2 Type/severity level (1 or 2 = corrected or non-fatal) -0x02 4 Data size -0x08 8 Pointer to error status block structure -0x10 8 Pointer to error source specific data -``` - -Entry count at `qword_3F90`.
